The ultimate energy storage system requires battery grade vanadium. Vanadium electrolyte remains in short supply as current production methods are unprofitable. VanadiumCorp is committed to addressing this industry demand with innovative solutions.

            VANADIUM REDOX FLOW BATTERY (VRFB) 
  • 20-25 year lifetime (No cross contamination as vanadium is the cathode and anode)
  • Contained vanadium electrolyte is 100% reusable and recyclable
  • Holds energy indefinitely (No thermal runaway)
  • No overheating, or possibility of fire or explosions (Highest safety rating)
  • Scalable (Capable of multi-megawatt/gigawatt storage)
  • Energy on demand 
  • High energy conversion efficiency (Best for storing renewable energy) 
  • Simple management and maintenance (no small battery cells!)
  • Best temperature range suitable for most climates

    Vanadium redox flow batteries (VRFBs) are fairly unique in the battery world.

  • They work by taking advantage of the natural properties of vanadium, a metal with four different oxidation states. But rather than using the metal in a solid state, vanadium electrolyte (a liquid solution) is used for both half-cells and the configuration is divided by a proton exchange membrane. Typically, massive tanks filled with vanadium electrolyte are connected, pumping the solution through at high volumes to charge or discharge.
  • THE BENEFITS OF VRFBS

    This unique setup gives VRFBs a few interesting advantages for something like grid-scale energy storage:

    • Extremely scalable
    • Can rapidly release large amounts of energy
    • Vanadium electrolyte is reusable, recyclable, and has a battery lifespan of 25+ years
    • No cross-contamination of metals, since only one metal (vanadium) is used
    • Cycle life is theoretically unlimited
    • Can maintain ready state for long periods of time
    • Can be charged and discharged at same time
    • Non-flammable

     

    As a result, VRFBs can be used in a variety of energy storage applications such as peak-shaving, load leveling, microgrids, wind and solar, off-grid power supplies, and uninterruptible power supplies.

    VANADIUM OUTLOOK

    VRFBs are getting more attention from utilities companies, and large battery projects have already been announced.

    The most notable vanadium-flow battery is probably a 200 MW system being built on the Dalian peninsula in China, which will serve 7 million residents. Costing $500 million, it’ll be used to peak-shave approximately 8% of Dalian’s expected load by 2020. This battery system will be the world’s largest, and it will single-handedly triple China’s grid-connected battery storage capacity.

    According to Chinese firm Azure International, the market projection for VRFB demand (by MW) in the top 10 countries is growing at an 80% CAGR from 2013 to 2020, ultimately culminating in more than 7,000 MW of vanadium-flow capacity needed in 2020.

    This demand could be even more substantial than that if the price of vanadium electrolyte could be reduced – it makes up about 30-50% of the cost of each battery alone.
